Unit 2- How Structure Influences The Properties And Uses Of Substances Flashcards
What do intermolecular forces do?
Makes single atoms stay together.
What are macro-molecules?
Giant covalent structures, have no ions
What is an alloy?
Two or more metals mixed
What is giant ionic?
Has charge, conducts electricity
What is a giant covalent?
High melting/boiling points, doesn’t conduct
What is a giant metallic?
Layered, conductor, has charge
What is a simple molecular?
Low melting/boiling points, doesn’t conduct
What are nano-particles?
Smart materials
What are fullerenes?
Hexagonally formed structures by atoms
What factors do thermosoftening polymers have?
Easily meltable and weak
What factors do thermosetting polymers have?
Strong intermolecular forces, strong cross links
What makes polymers?
Polythene
What are the two types of polythene?
Low density
High density
What two structures do covalently bonded substance form?
Simple molecule
Giant structures
What are polymers?
They are long lines of monomers (carbons)
